Patent JP-H03276922-A (JP)
Title: A/d converter
Inventor: TADA SHOICHIRO
IPC: H03M1/36
Filed: 1990-03-27
Abstract: PURPOSE:To reduce an A/D conversion error by connecting the input of each comparator of a comparator array in a holding state with a switch element of a 3rd semiconductor switch and plural circuit elements. CONSTITUTION:When an A/D converter transfers from a sampling state into a holding state, that is, each semiconductor switch element of a 2nd semiconductor switch element array 102 transfers from a conducting state to a cut-off state, a charge is injected to an input terminal of each comparator of a comparator array 3 from each semiconductor switch element of the 2nd semiconductor switch element array 102 via each semiconductor switch element of a 3rd semiconductor switch element array 103 and dispersion takes place in a potential the same as a case in figure 5 of a conventional example. However, since the input terminals of each comparator of the comparator array 3 are interconnected via each semiconductor switch element of the 3rd semiconductor switch element array 103 and the circuit element 4, the potential is averaged to reduce the error of A/D conversion.

Title: Photothermic and magnetic recording medium
Inventor: KISHI HIROYOSHI
IPC: G11B11/10
Filed: 1982-05-10
Abstract: PURPOSE:To obtain a photothermic and magnetic recording medium which has a Kerr rotational angle larger than the conventional value and high S/N along with easy producibility of film, by providing a 4-element amorphous magnetic alloy film of Gd-Tb-Fe-Co having an axis of easy magnetization on the film surface and in the vertical direction on a substrate. CONSTITUTION:Gd, Tb and Co pieces are arrayed evenly on Fe to obtain a target. Then a high-frequency sputtering device is used to form an amorphous magnetic alloy film consisting of Gd-Tb-Fe-Co having the sum of Fe and Co equal to 50-90% total of 4 elements in terms of an atom ratio on a glass substrate so that an axis of easy magnetization is obtained in the direction vertical to the film surface. It is preferable to set the composition of 4 elements within a range shown by an equation (0.005<=X<1.05<=Y<=0.9, 0<Z<1). As a result, the Kerr rotational angle is greatly increased in comparison with the conventional value with high S/N and excellent heat stability for a photothermic and magnetic recording medium.

Title: Expansion method and device
Inventor: HOSHINO KENZO
IPC: F01K21/02
Filed: 1989-03-31
Abstract: PURPOSE:To suppress temperature drop of working gas and enlarge expansion work by heating by pouring, from a nozzle, high temperature liquid over the surface of a piston when the piston is in its downward stroke. CONSTITUTION:In a reciprocating expansion machine, a piston 2 in a cylinder 1 moves toward a direction marked with an arrow 3, and gas flowed into the space ABQP from a valve 6 expands. High temperature liquid in a tank 14 is then pressurized with a pump 10, and poured over the surface PQ of the piston 2 from a nozzle 9. With the return of the piston 2, the high temperature liquid is discharged from a valve 7 together with exhaust gas, and brought back to a high temperature again with a heater 13 after passing through a passage 8 and an accumulator 11. Since the temperature drop of working gas can thus be avoided, the gas expands without experiencing any compression of its volume so that expansion work can be enlarged.

IPC: G06F9/445
Filed: 1983-05-06
Abstract: PURPOSE:To perform the processing even outside the service time of an operator and to improve the working efficiency by providing a control means which collates the designated time stored in a memory with the time of a time point device and executes a selector processing program. CONSTITUTION:When the name of a processing program to be executed and the execution start time are supplied by a console input device 4, a main controller 1 stores them to an internal program execution time table. The controller 1 receives an interruption every fixed time from a time point device 8 and replaces and stores a time point after interrupting a program which is under execution. This stored time point is collated with the contents of a program execution start time table. If the execution start time elapses, a magnetic memory 3 is retrieved to read the program main body to load it to a program memory area of an RAM. This loaded program is executed in parallel to the interupted program. In such a way, a program is selected along with designation of the execution start time. As a result, the processing can be executed automatically and the working is possible even with absence of an operator.
